SPECIFICATION forming part of Letters Patent No. 699,970, dated May 13, 1902.

Application filed February 17, 1902. Serial N0.94,354. No model.)

To all, whom it may concern.-

Be it known that I, GEORGE E. PIoKoP, a citizen of the United States, residing at New' Britain, county of Hartford, State of Connecticut, have invented certain new and useful Improvements in Detachable Hinges, of which the following is a full, clear, and exact description.

My invention relates to hinges.

The object of my invention is to provide a construction by which a screen-door, storm window, or the like which it is desired to remove from time to time may be readily renioved without unscrewing or separating the hinge-leaves.

The invention relates particularly to that type of hingestermed spring-hinges, by which I mean hinged provided with springs or the like, so that the door or window to which they are applied will be self-closing.

In-the drawings, Figure 1 is an elevation of the hinge of my improved construction as it appears in operation. Fig. 2 is a plan view thereof, partlyin section. Fig. 3 is an elevation of a detail of construction. Fig. 4is a plan View of Fig. 3. Fig. 5 is an elevation of amodification. Fig. 6 is an elevation of a detail of construction of the modified form adapted for use with the hinge shown in Fig. 5. Fig. 7 is a plan view of the parts shown in Fig. 6.

A represents the edge of a door.

B represents the adjacent edge of adoorcasing.

0 represents one hinge-leaf. D represents another hinge-leaf, secured to the hinge-leaf C by the usual pintle-bearings and pintle E.

F is a spring of any approved pattern, by which the hinge-leaves O D are caused to move, so that when applied the tendency of the spring F will be to close the door or window to which the hinge is applied. One of the hinge leaves-for example, Dis provided at its rear side with an undercut groove wider at its lower end than at its upperend.

G is a wedge-shaped keeper of an outline,

corresponding to the outline of the recess to the rear of the hinge-leaf D. Screw-holes G may be provided in said keeper G. As shown,

the leaf C is screwed to the door A and the keeper-plate G is screwed to the casing B.

.To attach the door A in place, the hinge-leaf D is slipped over the keeper-plate G and slid down upon the same until an effective engagement is securedbetween the parts D and C. In the preferable construction the leaf D is provided with openings in the face thereof slightly larger than theheads of the screws by which the keeper-plate G is secured. By.

this means the fitting and application of the hinge are very much simplified and expedited, since it obviates the'necessity of fittingthe keeper-plate G to the casing B separately from the hinge. In other words, by this con stru'ction the keeper-plate G is inserted into place in the rear of the hinge-leaf D. The

screw-openings will come opposite the windows in the hinge-leaf D. The carpenter may then insert the screws in place in the usual manner in which they are inserted in that the screw-heads will pass through the plate D and engage in the keeper-plate G. WVhen the parts are secured in position, itis simply necessary to lift the door or the hingeleaf D to slide it off and out of engagement with the said keeper.

In Figs. 1, 2, 3, and 4. the keeper-plate G is tapered throughout its length, and to prevent excessive jamming and to afford a neater fit the opposite edges of the keeper-plate are preferably cut away or recessed, as shown at G so as not to engage with the leaf D. Thus when the parts are assembled only the upper and the lower ends of said keeper-plate contact with the hinge-leaf.

In Figs. 5,, 6, and 7 Ihaveshown a modification in which the keeper-plate is tapered through only about half its length. Inother words, the keeper-plate proper is only about half the length of the hinge, since it is only that portion of the keeperplate which is tapered which constitutes'the holding device.

In the form shown in Figs. 5 to '7, inclusive, G is the keeper-plate, which may be fastened to the door or door-casing in the manner before described. The leaf D is provided with:

an undercut recess in the rear thereof, the

70 all hinges, and the windows are of such asize outline of which generally approximates the shape of the hour-glass. In this construction the pitch or taper of the keeper G is more abrupt than the pitch or taper of the keeperplate G. Consequently there isless likelihood of jamming of the parts. Furthermore, the hinge-leaf D may be more readily separated from the keeper-plate Gr than could the leaf D be separated from the keeper G. This is due to the lesser tendency of the jamming and also to the fact that half the movement entirely separates said parts. Another advantage is gained by the construction shown in Figs. 5, 6, and 7 in that the hinge may be used either as a right or left hinge, it being merely necessary to attach the keeper-plate G so that its narrower portion will be uppermost. This I deem asubstantial advantage, since it obviates the necessity of manufacturing both right and left hinges. In the construction shown in the modification the hingeleaf D is also provided with windows sufficiently large to admit of the passage of the screw-heads.

What I claim, and desire to secure by Letters Patent, is

1. A hinge comprising a pair of leaves, one of said leaves having an undercut tapered cavity in the rear side thereof, and a detachable keeper-plate projecting into said cavity and secured thereto, said cavity being of an hour-glass shape, the keeper being adapted to engage in either end of said cavity.

2. A hinge comprising a pair of leaves, one of said. leaves having an undercut tapered cavity in the rear side thereof, and a detachable keeper-plate projecting into said cavity and secured thereto, screw-passages in said hinge-leaves and in said keeper-plate, said passages in the leaf bearing said plate being sufficiently large to permit of the passage of the screw-head.

Signed at New Britain, Connecticut, this 12th day of February, 1902.
